Hello Harleybiker! I recently decided to refuel my Softail Deuce Injection with Shell V-Power (100 Oktan). The fuel is a lot more expensive, but should also bring more power and less fuel consumption. I have now driven a complete tank empty and actually got a good 80 kilometers further. I also subjectively the impression that my bike “switches off” better. The consumption was exactly 5,2 l / 100 km. – Has someone made similar experiences with the Supersprit ? – Can the Supersprite hurt the engine ? – Do I have to fill in the Supersprite now ? Thanks in advance for your answers
